The Toads don't draw flies. I don't know how many -- if any -- sellouts they had last season. When we played down there two years ago in the last game of the season, and TCU had a bid to the playoffs on the line, the place was probably a fourth empty. When we played them a few years ago in a bowl game, I think there were damned near as many ISU fans as TCU fans.....and the game was in freaking Dallas.
Having said all that, I got the impression from watching on TV that a lot of people left at halftime (it was 24-7 and uncomfortably hot).
Still, it's amazing to me that with the success the team has had and the population base, they draw maybe two-thirds as many fans to their games as Iowa State, which hasn't exactly been a world-beater the past few seasons (or forever).
